The area of the triangle is 
a=( m x n) /2  in cm² , implies   2xa = m xn
the area of the rectanglle
A= n x m  in cm²
but we know  <span>  2xa = m xn = A,  </span>
that means  the surface of the rectangle is 2 times of the area of the triangle

Answer:

\text{Area of triangle}=\frac{1}{2}\text{Area of rectangle}

Step-by-step explanation:

In triangle TRI

Height of triangle = n

Base of triangle = m

Formula of area of triangle = \frac{1}{2} \times Base \times Height

Area of ΔTRI = \frac{1}{2} \times m \times n

In rectangle RECT

Length = n

Width = m

Formula of area of rectangle = Length \times Width

Area of rectangle RECT= m\times n

On comparing Area of triangle and rectangle.

We can conclude that area of triangle is half of the area of rectangle .

\text{Area of triangle}=\frac{1}{2}\text{Area of rectangle}
